Title:
HIGH-FREQUENCY MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/116970
Kind Code:
A1
Abstract:
An array antenna (13) comprises: a plurality of first patch antennas (11) that each radiate an X-direction polarized wave at a first operation frequency, and radiate a Y-direction polarized wave at a second operation frequency higher than the first operation frequency; and a plurality of second patch antennas (12) that each radiate the Y-direction polarized wave at the first operation frequency, and radiate the X-direction polarized wave at the second operation frequency. When the distance between an arbitrarily defined first patch antenna (11) and another first patch antenna (11) closest to the arbitrarily defined first patch antenna (11) is denoted by D1, and the distance between the arbitrarily defined first patch antenna (11) and the second patch antenna (12) closest to the arbitrarily defined first patch antenna (11) is denoted by D2, D1>D2 holds.
